QGMBENATIQN-LOCK AND CIRGUIT- BBEAKEB.

To all whom it may concern:

Be it known that I, Grocer; J. BUCKEYE, a citizen of the United States, residing at Kansas City, in the count-y of Jackson and State of Missouri, have invented certain new and useful Improvements in Combination-Locks and Circuit-Breakers, of which the following is a specification.

This invention relates to improvements in combination locks and circuit breakers, and embodies a combination of novel 'features hereinafter described, and particularly pointed out in the claims.

The primary object of-the device is to prevent unauthorized persons from closing the electric circuits of automobiles, so that they will be unable to operate an automobile provided wit-h my device.

'lhe device can be used to equal advantage on electricdriven, or gasolenedriven auto-mobiles, and in order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which:

Figure 1 is a front elevation of the device. Fig. 2 is a rear elevation of the device with a back plate'forming a. part thereof, removed to show the interior mechanism. 3 showsa group of tumblers employed in carrying out the invention; Fig. 4' is a vertical section on line IV-IV of Fig. 1, and Fig. 5 discloses one form of circuit to which my device is applicable.

Referring in detail to said circuit, 46 discloses a starting box; 30 and 31', the circuit breaker and its contact of my device, said contact being connected to the starting box bya wire 49 and 50, a circuit breaker and its contact, controlled by a cam on the engine shaft; 43 a wire connecting the contacts 31 and 45 a magneto; 41 a wire connecting the circuit breaker 49, with said'ma neto' 47 a batte 44 a wire connecting battery 47 and wire 41; 48 a manual switch; 41 and 44, contacts atthe free terv cular flange 11, and a stem 12. Flange 11 16a minals of wires 41 and 44, respectively; 'and 51, a push button for controlling communication between Wires 41 and 43. The operation is substantially as follows: When the parts are in the position shown on Fig. 5, impulses may be transmitted to the spark plug of the engine (not shown) by throwing switch 48 into engagement with; contact 44. This will establish a circuit from Specification of Letters Patent.

battery 47, through wire 44, switch 48, (in

cuit box 46, wire 40, members 30, and 31,

wire 43, push button 51, and from wire 41 to Wire 44, back to the battery '47. By manipulating the push button 51 the necessary impulses are transmitted to the spark plug until the engine isunder way, after which the battery 47 is cut out and the magneto 41 cut in by throwing switch 48, into en- I gagemen't with contact 41*. Further manipulation' of the push button 51, is unnecessary, as the circuit breaker 49, thereafter controls the transmission of impulses to the sparkplug, said-circuit breaker being vibrated by the cam on the engine shaft in the well known manner.

' In constructing the look, I employ a cylindrical casing 1, having an integral face 2, and a removable back-plate 3 normally held in position by two screws 4, the heads of which are countersunk in the back plate, as shown by dotted lines, Fig. 4. The inner sides of easing 1 and back plate 3 are pro tected by insulations 5 and 6, to preventshort circuit-ing of the current hereinafter referred to. Back plate 3 is provided with a pair of stud-bolts 7, adapted to extend through the dash-board of an automobile (not shown) and be secured by nuts 8, which may be hidden by the engine-hood of the automobile. By thus hiding nuts 8, itwill be exceedingly difiicult for unauthorized persons to locate the same, and as screws 4 can not be removed from the backplate until the device is taken from the dash-board, access can not be had to the inso terior of the casing containing the tin elock and circuit breaker mechanism.

Face 2 of easing 1 is provided with a concentric annular dial 9, which is countersunk in said face and consists, preferably, of celluloid; or other light-colored material, so that the black graduations thereon can be readily distinguished.

1Q designates a knob provided with a cirportion of flange 11, which hasa marginal recess 11, to receive the adjacent edge of dial 9.

Stem 12 extends through the central raised portion of face 2 and is journaled in a bearing 16, extending inward from the inner side of face 2, the inner end of stem 12 being reduced to form a shoulder 17, and threaded to receive a pair of jam-nuts 18, whereby a tumbler 19 is firmly locked against shoulder 17, so that it Will turn with stem 12 and knob 10.

Knob 19 is provided with a laterallyextending eccentric-pin .20 adapted to coact with one side of an eccentric-pin 21, extend 'ing laterally from opposite sides of an intermediate tumbler loosely-mounted on hearing 16 and having a peripheral notch 23. The side of pin 2.1 opposite from pin 20 is adapted to r-oaet with an eccentric-pin 2 extending laterally from a tumbler 25, loosely-mounted on bearing 16 and provided with a peripheral notch 26 adapted to regis ter with the notch 23. Tumbler 19 has a lon radius 27, and a highradius 28, the lowest point of radius 27 being on a. level with the bottom of notches 23 and 26, While radius 28 is on a level with the peripheries of tumblers casing 1. Arm 30 is pivotally-mounted upon a screw and divided into two sections S-l and by insulation 36 to prevent current passing from section 34 to section 35, thence to the tumblers and other portions or" the device, through the intermediacy of a downturned tooth 37 integral with section 35.

Arm 30 is pressed toward contact 31 by a spring 38, and provided at its forward portion \\'1tl1 it binding-post 39 to secure the terminals of two circuit wires #10 and 41.

A rm has a binding-post 12, to receive the terminals 0t two circuit-wires 43 and 44;. Circuit-are 41 leads to a magneto 45, cir- -cuit-wire e3 leads to a starting-box 46, and

ciircuitwvireslo and 14 also lead to the starting-box 46, wire ll communicating- With a battery 47. The magneto 4C5 and the starttumblers 22 and 25 until their in meager ing-box 46 are of ordinary type and connected in the usual manner to a spark-plug; (not shown), a detail description thereof is deemed unnecessary.

In the drawing the circuit-breaker is shown closed. VVhen it is desired to open the circuit-breaker tumbler 19 is turned until its higlrradius 28 passes beneath teeth 3'? and aises the same out of the notches and 26 of the tumblers 22 and 25, respec ivoly.

Knob 10 may then be turned t the from beneath the tooth 37, s may rest upon the peri :herie lolers and thus support gagement with contact breaker can not then 0105 l is properly manipula ed blers to the position shown i merous combinations in 1y "ad by simply loosening nuts 18 and-ttnnit. tumbler 19 to difierent points on 12.

l -(hile I have shown and do 'zri'b'ui the de vice for use in controlling tn .llCllll; of an aut-on iobile i, of course, do not Wish to be limited. to this use, since it is obvious the device can be employed to advantage in opening and closing various kinds of circuits.

Having thus described my invention,

I claim and desire to secure by Letters cnt is:

1. In combination a'device of the eharacter described consisting of a casing, a circuit-breaker therein comprising a stationary arm and a movable-arm said movable arm comprising two sections L i by non ducting material, one of said sections having a tooth, tumblers to control 5 id movable arm and means for actuating said tumblers.

2. In combination, a device consisting of a casing, a circuit interrupter therein comprising a stationary contact and a, pivoted arm carryin a cooperating contact, said arm being provi ed with a tooth, and permutation tumblers mounted in said casing to co act With said tooth to control the movement of said arm.

In testimony whereof Z atiii; my signature in the presence of two Witnesse.
